WRAPPER-SEALING MACHINE.

Specification of Letters Patent. Patented J M11143 7, 1921 Application filed January 15, 1921. Serial No. 437,434.

To all whom it may concern:

Be it known that I, DAVILA'S. DU BRUL, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Wrapper-Sealing Machines, of which the following is a specification. r

The present invention relates to a machine for sealing the ends of a wrapper applied to an article, such as a cigar, sometimes referred to as the operation of foiling the cigar, and has for its object to provide a simple and efficient machine serving this purpose.

()ne feature of the invention consists in providing apair of oppositely presented, preferably coaxially alined, spinning thimbles with means for mounting and rotating them at a speed that will spin out and closely seal the wrapper upon the ends of an article, such as a cigar, which the thimbles are constructed to receive. 7

Another featur consists in providing a plurality of these thimbles having varying designs of spinning cavity, and mountlng them interchangeably in a pair of oppositely presented cups, preferably coaxially alined, and constructed to receive and hold the thimbles and impart rotation thereto.

Still another feature of the invention relates to the manner of mounting the cups and imparting positive rotation thereto.

In the accompanying drawings Figure 1 is a front elevation of a machlne embodying the several features of the present invention, with the table upon which the machine is mounted and the parts at one end shown in axial section.

Figs. 2, 2 and 2 are sectional detail views of a series of thimbles with differently designed spinning cavities respectively adapted to be mounted in position to receive and spin the point or mouth ends of cigars; and Figs. 8, 3 and 3 are similar views of thlmbles for spinning the butt or lighting ends of cigars;

Fig. 4 is a plan view of the machme; and

Fig. 5 is an end View of the same.

1, 1, represent a pair of spinning thlmbles, co-axially alined in opposed pos tions, spaced apart to permit a wrapped article to be introduced between them, and constructed with spinningcavities of such shape as to substantially conform to the ends of the axis of the spinning cavity.

ported in a pair of spaced standards 5, 5,

with a driving pulley fixed upon the spindle between the standards. Each spindle is preferably constructed with a shouldered enlargement 7 adjacent the standard 5, and

in a position to abut against ball bearing 8 mounted in the standard 5 and surrounding the reduced portion of the spindle, so that the ball bearing thus serves as a thrust bearing as well as a radial bearing. A second ball bearing 9, mounted in the standard 5* around the outer end of spindle 4, assists in fixing the alinement .of the spindle at the The foregoing details of construction de scribed in connection with the sectional illustration at the right-hand end of the machine, are1 preferably duplicated at the left-hand en i In order to impart rotation to the cups 2 which carry the thimbles 1, belts 10 connect the pulleys 6 with suitable pulleys'll on a common drive shaft 12, which has its ends mounted in the hangers 13 preferably equipped with ball bearings 14, as shown in section at the right-hand end of the shaft; and this shaft 12 is driven from any suitable source of power, as, for instance, from an electric motor 15, mounted beneath table 16 and connected with the shaft 12 through belt 1? and pulley 18.

In order to oppose inward axial displace ment of the spindle 4, it is provided on its outer end with jam nuts 19 threaded to the spindle. Similarly, shaft 12 is fixed against axial displacement by means of am nuts 20.

In order to effectively inclose the bearings of the spindles and shaft, intermediate caps 21 and end caps 22 are mounted upon the faces of standards 5, 5 and shaft hangers 13; the intermediate caps 21 being perforated to receive the revolving member around which they are fitted, and the end caps 22 being continuous so as to completely inclose the end of the shaft or spindle, its

ball bearings, and jam nuts. The caps 21 and 22 are preferably secured in position by means of bolts 23 passing through one cap and threaded into an opposite cap.

A machine constructed as above described affords convenient and eflicient means for spinning the ends or" cigar wrappers, or other like articles and to effectively seal the ends of the wrapper, particularly when such articles are wrapped with metal foil. By substituting in the cups 2, spinning thimbles with cavities properly selected to suit the particular shape of cigar end, the machine may be used for foiling or sealing a Wide variety of cigar shapes.

I claim:

1. In a wrapper sealing machine, a pair of oppositely presented foil spinning thimbles adapted to receive the respective ends of an article to be sealed, and means for positively rotating said thimbles.

2. In a wrapper sealing machine, a pair of oppositely presented foil spinning thimbles adapted to receive the respective ends of an article to be sealed, and means for positively rotating said thimbles both in one direction. V

3. In a wrapper sealing machine, a pair spective ends of such article, and having means for positively rotating them.

4:. In a wrapper sealing machine, a pair of coaXially alined, oppositely presented spinning thimbles, cups receiving and holding the respective thimbles, and means imparting rotation to the cups.

5. In a wrapper sealing machine, a pair of spinning cups, spindles upon which said cups are mounted, presenting said cups in coaxial alinement with their open ends 0pposed, standards upon which the respective spindles are rotatably mounted, and a common drive shaft having driving connection with the respective spindles.

6. In a wrapper sealing machine, a pair of opposed coaxially alined cups having means for rotating them, and a series of variously designed spinning thimbles inter- I changeably adapted to be held and rotated by said cups.
